In the Mammalia, New South Wales exhibited a collection 
of marsupials. In the annex to this country's exhibit, on the 
west side and directly across the aisle from the main exhibit, 
there were some line casts of the mandible, femur, pelvic gir- 
dle, etc.. of Diprotodon australis, the only species of this ex- 
tinct family at present known and the largest of the entire 
Marsupialia. Locality: Pleistocene, near Myall creek. Bin- 
gera. The pelvic girdle shows the so-called marsupial bones ex- 
tending upward from the symphysis. In tire catalogue there 
are no less than 113 specimens of various parts of Macropus 
(Kangaroo), NotQtherium (which is similar in many re- 
spects to Diprotodon), Thylacinus (Tasinanian wolf), Thyla- 
coleo (Phalangers), Phascolomys (wombat) and Sarcophilus, 
In the Brazilian exhibit there were bones of the Mastodon 
and Megatherium americanum from Bahia, and of Mastodon 
from Ceara, and the Japanese section exhibits teeth of Ele- 
phas primi genius. 
Besides these, there are restorations and casts in the United 
States Government building and more particularly in the 
Anthropological, as well as photographs and a few casts in 
tlie Mining and in the galleries of the Liberal Arts buildings. 
It is to be regretted that the casts of some of the most re- 
markable species in our extinct mammalian and reptilian 
faunas were not exhibited.
